ELECTRICAL ROSETTE.

Y' county of New York and State of New York, have invented certain new and useful Improvements in `Elec- 'trical Rosettes, of which the following is a full, clear,

'and exact description.

'l My invention relates to rosettes or electric wiring, and particularly those used in connection with cleat 'wiring l The principal object of the invention is to provide a rosette in which any strain on the dependent `cords or wires is resisted by a positive and unyielding abutment so thatstrain is not imposed on the terminal'screws o1' connections.

'ak-further object of the invention is to-provide a rosette which serves as a support for the circuit wires and .maintains themv in proper spaced relation from the ceiling or supporting surface, and whichA conforms to With these and other objects in View, the invention all the insurance regulations.

` A still further object of the invention is to provide a simple, compact and easily constructed rosette, which is strong and durable and easy to assemble into place.

consists in the construction, combination, in the location and in the arrangement o f parts, as hereinafter set .orth and shown, and finally particularly pointed out inthe appended claims.

...In the drawings: Figure l is a plan or'face view of a.

rosette embodying the principles of my invention with hecover removed; Fig. 2 is a side view of the same;

FigfB is a sectional view through the cover showing the parts beneath, partly in side elevation.

In cleat wiring, it is customary to stretch the circuit Wires along a ceiling, or suitable supporting surface, by means of spaced insulating supports to which the Wires are attached. In this way the circuit Wires aremaintained at all points at a certain spaced distance over 'thesupporting surface, the amount of such distance bcing prescribed by the insurance regulations. The

' lamp circuits are made by branch connections depending from the circuit wires at suitable points, and at the point of attachment oi such depending lamp connections, it is necessary to have specially constructed xwell. I also provide a construction which is adapted to resist the weight of thependent cords and lamps and `any strains which may be put thereon against a positive or'unyielding abutment, so that the connection of the wlieswith the terminals is not endangered by such strains. 'In carrying out the inventionI make use of a Specification of Letters Patent.

. porcelain block which is recessed or channeled in a special Way, so as to provide a locking or gripping surface to resist strains on the dependent connections; l also provide certain metallic clips organized into the insulating block in such a way as to serve the double purpose of fastening/the circuit wires and the dependent lamp connections in piace, and establishing an electric circuit between them.,

Referring now to the drawing in which like parts are designated by the same reference sign, l indicates a block of porcelain or insulating material, anzdwhich is preferably rectangular in outline and oi a width about equal to the distance of separation of thecircuit wires. The end walls 2 of this block are recessed or channeled,

as shown at 3, the form of such channels being conveniently enlarged at their central portion 4i 5 indicate vertical passages or openings extending vertically through the block and communicating with the channels 4. The metallic clips which constitute the rosette connections are passed through these holes and have means by which they are attached to the material ofthe block. These metallic clips are' designated at 6 in the drawings, and in their preferred form comprise strips oi instal bent right angularly at the respec.- tive ends 7 and 8, the bent portions extending on opposite sides oi the strips. The portions 8 extend into the holes or passages 5 above mentioned, and have terminal screws 9 for connection with the circuit wires l0. Theother end 7 of each clip lies against a wall ll, oi a protuberance l2, on the block l. I3 indica-te screws which may be passed through the clips at the part 7 and iastened Within the protubersnce l2. In practice l make use of nuts 14, which may be embedded in the pretuberance l2, to engage each screwl for this purpose. The screws 13 serve a double function of holding the clips in place and forming a means for the connection of the lamp circuit wires. The protuberance l2 is incut with 1i. slot or recess l5 on each side, `which isprcierably curved or bent in direction, as illustrated in Fig. 3, and which leads from the upper surface 1G oi the protuberance to\a point l7, adjacent to each terminal screw. The form of these slots l5 .is such that the extension wires l8for the lamps may be placed therein, in which relation they are deliected into a position to be readily clamped beneath the terminal screws 13.

Referring particularly to Figs. l and 3. it will be seen that the slots 15 terminate on the upper surface 1G of the protuberance l2, at points which are separated more widely than the normal distance of separation of a pair of cord Wires. l provide means for bending the wires sharply at the points oi their emergence frein the slots l5 in order 'to secure a bight in each wire to resist any strains put upon the lamp connection. For this purposel conveniently malte use oi a' cover 19, which tits over wlt'tehthe lamp connections are made.

the entire block l t' being properly recessed for the c irouit wires l0) and which has an opening 20, through 2l indicates a bushing oi insulating material which is contained in the opening 20.and which closely surrounds the Connection 22 oi this bushingis prelerablyilat. and the size o the central opening is just ln this Way the lower surface 22 ot' the bushing serves as a shoulder to (leiter-t the extension wires 18 downward upon the flat fat-e 'lli ol the protnberance l2. ln` this way 'the wires are sharply bentI at a point immediately beneaththe bushingand any strain which is put on the wires is taken by the bushing and by the housing to which it is attached. The rosette may be fastened in position in any desired way. For example. l may employ ordin'ary wood screws passed through suitable holes in the cover and through holes 23 inthe block l, so as to he engaged in the ceiling or supporting surlaee.

A feature. ot the invention relates to the construction ol the housing '19. This may be made of any suitable niatzerial. but l prefer to construct` this housing oi sheet Inet al stamped to the required form in a. die press7 and afterwards coated with a vitreous or stoneware coating, so as' to make the housing insulating in character. and highly ornamental in appearance. ln this way the portions ol the interior parts oi the rosette may bemade ample 'lor strength and safety. and yet the complete article will be very compact and pleasing in appearance.

The use and operation is as t'ollows: The circuit wires l() are bared t'or a short distance at the required points, and the bared portions are clamped beneath the terminal screws i) on either side oi the rosette. The lower end oi the extension 8 ol each clip (i may be conveniently deflect ed to iorm an ear 8/ against which' the circuit. wire rests to pret-little any displacement. lt is now merely necessary to clamp the two ends oi the ext l l,

tension wires i8 beneath the terminal screws i3, the

wires being then embedded in the slots l5, and twisted as tightly as possible above the the housing lit is now positioned, the bushing 2l bears downward upon the extension wires l8,and defiects protuberant-e l2. When them into a sharp bend or bight as above described. The fastening screws are now passed through the openings 23, and the rosette is eotnplete and ready for use.

While l have described my invention with particular reference to its use in cleat wiring` l do not desire to be limited or restricted thereto, since it is evident that it is applicable to molding wiring, and all places where extension lines or branch connections l'roxn a pair ol circuit wires are desired.
